I'm trying to configure Etherchannel on AIX 5.3 and I'm having some problems. I am aggregating both of the onboard NIC's (ent0 and ent1) into a new adapter ent2 for failover reasons obviously. At first I was experiencing a problem where about 50% of all my packets would be dropped. Then after... (4 Replies)

Nagios server pings every server in the data center and we have pretty much every known unix flavor in this data center. When... (3 Replies)

HY(4) Kernel Interfaces Manual HY(4)
NAME
hy - Network Systems Hyperchannel interface
SYNOPSIS
/sys/conf/SYSTEM:
NHY hy_controllers # Hyperchannel
DESCRIPTION
The hy interface provides access to a Network Systems Corporation Hyperchannel Adapter.
The network to which the interface is attached is specified at boot time with an SIOCSIFADDR ioctl. The host's address is discovered by
reading the adapter status register. The interface will not transmit or receive packets until the network number is known.
DIAGNOSTICS
hy%d: unit number 0x%x port %d type %x microcode level 0x%x. Identifies the device during autoconfiguration.
hy%d: can't handle af%d. The interface was handed a message with addresses formatted in an unsuitable address family; the packet was
dropped.
hy%d: can't initialize. The interface was unable to allocate UNIBUS resources. This is usually due to having too many network devices on
an 11/750 where there are only 3 buffered data paths.
hy%d: NEX - Non Existent Memory. Non existent memory error returned from hardware.
hy%d: BAR overflow. Bus address register overflow error returned from hardware.
hy%d: Power Off bit set, trying to reset. Adapter has lost power, driver will reset the bit and see if power is still out in the adapter.
hy%d: Power Off Error, network shutdown. Power was really off in the adapter, network connections are dropped. Software does not shut
down the network unless power has been off for a while.
hy%d: RECVD MP > MPSIZE (%d). A message proper was received that is too big. Probable a driver bug. Shouldn't happen.
hy%d: xmit error - len > hy_olen [%d > %d]. Probable driver error. Shouldn't happen.
hy%d: DRIVER BUG - INVALID STATE %d. The driver state machine reached a non-existent state. Definite driver bug.
hy%d: watchdog timer expired. A command in the adapter has taken too long to complete. Driver will abort and retry the command.
hy%d: adapter power restored. Software was able to reset the power off bit, indicating that the power has been restored.
SEE ALSO
intro(4N), inet(4F)
BUGS
If the adapter does not respond to the status command issued during autoconfigure, the adapter is assumed down. A reboot is required to
recognize it.
The adapter power fail interrupt seems to occur sporadically when power has, in fact, not failed. The driver will believe that power has
failed only if it can not reset the power fail latch after a ``reasonable'' time interval. These seem to appear about 2-4 times a day on
some machines. There seems to be no correlation with adapter rev level, number of ports used etc. and whether a machine will get these
``bogus powerfails''. They don't seem to cause any real problems so they have been ignored.
